Over 100 trees were blown over, at least eight cottages had trees across the roofs and others had outbuildings damaged. One cottage had most windows blown out and it was blown off of it's foundation and likely will have to be completely demolished and rebuilt. One other huge cottage had at least 4 trees on the roof and suffered major damage. A number of boats and docks were blown onto the shore and destroyed. A 19 foot inboard/outboard boat was blown off of it's lift and flipped upside down into the water and the lift was blown upside down into the lake. (thanks to Peter C. for the description)

(located NW of Dryden in north western Ontario) Dave Sills of EC writes ..."The MNR is mapping out damage from what appears to be a tornado. A long swath of conifers several hundred metres wide levelled, and a photo of a funnel cloud to boot! I'll be writing up that report as well and should have something on that soon."

Tornado struck early in the morning, downing trees and power lines, damaging houses and destroying a few horse barns.

Thunderstorms by MonthBefore only a colour was used to designate a severe thunderstorm warning, but many times a warning was issued accompanied by only a weak storm. So in previous years I've kept records it was hard to tell if the storm was in fact severe just by looking at the table. This year an "X" will be placed into the box if a warning was issued by Environment Canada but no severe t-storm or tornado actually occurred. Warnings are defined as "imminent or already occurring" and I wish in the future E.C. would abide by this. Imminent of course meaning, it *IS* going to happen. Not a chance it's going to. That's what watches are for.
